+# ThingiPrint
+
+**ThingiPrint** is a benchmark dataset that links CAD models to real photographs of their 3D-printed counterparts.  
+It is intended as an evaluation benchmark for 3D-printed object classification, focusing on generalization to previously unseen object instances.

+
+## Object Overview
+
+The figure below shows example objects from the ThingiPrint dataset.
+
+![ThingiPrint object overview](ThingiPrint_objects.png)
+
+---
+
+
+## Dataset Contents
+
+ThingiPrint consists of real images of 3D-printed objects corresponding to CAD models sourced from the Thingi10K dataset.
+
+### Main Dataset (100 Objects)
+
+- 1000 real images total
+- ~10 images per object
+- Objects printed using an industrial SLS printer (Sindoh S100)
+- Material: white PA12 (polyamide 12)
+
+
+### Auxiliary Dataset (20 Objects)
+
+To evaluate robustness to manufacturing variation, a subset of objects was reprinted using a different printer and material.
+
+- 200 additional real images
+- ~10 images per object
+- Printer: Prusa MK4
+- Material: white PLA
+---
+
+Loading the dataset:
+
+```python
+from datasets import load_dataset
+
+# Load the Main dataset (100 objects)
+ds_main = load_dataset("fanismathioulakis/thingiprint", "main")
+
+# Load the Auxiliary dataset (20 objects)
+ds_aux = load_dataset("fanismathioulakis/thingiprint", "auxiliary")
+
+# To access an image from the main set:
+sample = ds_main["test"][0]
+image = sample["image"]
+label = sample["label"]
+```
+
+
+## Data Organization
+
+The dataset follows a folder-per-object structure where each folder name corresponds to the **original Thingi10K CAD model ID**.
+
+```text
+ThingiPrint/
+└── test/
+    ├── 34785/  <-- Thingi10K Model ID
+    │   ├── 01.jpg
+    │   └── ...
+    ├── 36069/
+    └── ...
+```
+
